Public bug reported:

If instance.save() is used to migrate the flavor from sys_meta to
instance_extra, this only works in that instance already has an
instance_extra row.

In the case where its missing, the update call silently fails to make
any changes to the database, and you get lots of OrphanedInstanceErrors
when listing instances, because the instance no longer has any flavors.
